Management of exhaust gas and reduction of greenhouse gases
The Company produces urea and methanol with natural gas and coal as raw materials, and ammonium phosphate (monoammonium phosphate and diammonium phosphate) and compound fertilizer with phosphate ore, sulfur and synthetic ammonia as raw materials, with the main emissions of CO2, SO2, NOX?and other exhaust gases. The Company strictly implements the Law of the People's Republic of China on Prevention and Control of Air Pollution, Comprehensive Emission Standards for Air Pollutants, Emission Standards for Air Pollutants from Thermal Power Plants, and other regulations and standards. The production units meets the SO2, NOX?national environmental protection emission standards, and focuses on promoting the flue gas treatment of coal-fired boilers and other major environmental protection treatment projects, greatly reducing the emission of air pollutants.

Wastewater management
The Company's wastewater mainly comes from industrial wastewater and domestic sewage. The Company complies with the Standards of Emission Standards for Water Pollutants in Ammonia Industry, Emission Standards for Pollutants in Petrochemical Industry, Emission Standards for Pollutants in Petroleum Refining Industry, etc., and strictly treats industrial wastewater and domestic sewage to achieve the standard discharge. It improves the efficiency of wastewater reuse and reduces the wastewater discharge. The Company's cumulative emission of Chemical Oxygen Demand (COD) in 2023 was 42.08 tonnes and ammonia nitrogen (NH3-N) was 0.60 tonnes.

Disposal of solid waste
The Company’s non-hazardous waste mainly consists of solid waste such as boiler ash produced during the production process, while the hazardous waste mainly consists of catalysts used in the production of products. The Company attaches great importance to the generation and disposal of hazardous and non-hazardous waste, strictly implements the General Industrial Solid Waste Storage and Disposal Site Pollution Control Standards, Hazardous Waste Storage Pollution Control Standards and Hazardous Waste Management Regulation and other requirements, standardizes the collection, storage, declaration, transfer and other activities of hazardous waste to develop relevant management systems and processes. The Company adopts anti-dispersion, anti-volatilization, anti-loss, anti-leakage or other measures to prevent environmental pollution, avoid environmental pollution caused by sprinkling, and entrusts units with national environmental protection qualifications to handle hazardous waste professionally, and the safe disposal rate reaches 100%. Due to the Company's production pattern, solid waste production is uncertain and it is difficult to set a clear reduction target, but the Company will continue to carry out safe disposal and maintain a 100% safe disposal rate.
